If one or both belts at the exit end of the machine travel to the left or right, the belt lagging on the
drive rollers must be replaced.
To replace the belt lagging, first remove the belt that is traveling out of line. Turn machine on and
with a utility knife, cut about 1/8" off the belt lagging with the point of the knife while the drive roller is
turning. Be sure to place the knife on the roller so that the roller is moving away from the point of the
knife, lift up a section of the cut lagging and pull off until it is removed from the drive roller completely.
This can be done by jogging the machine on and off while pulling the cut strip of lagging. Attach new belt
lagging. Replace the belt and check alignment. The belt will have moved to the opposite side that was cut.
This procedure may have to be repeated until the belts are centered.
Belt drive system - heavy duty
The two belts are driven by a belt pulley system connected to the gear reducer through a chain
drive system. If the chain becomes loose, loosen four reducer bracket screws and drop reducer down until
chain becomes tight. Tighten screws when adjustments have been made.
The belts at the infeed end of the machine travel over the tension rollers. The tension roller
brackets hold two guide rollers each that automatically center each belt. The belts then travel over the idler
roller located at the infeed end of the machine. To replace a belt, bring the belt lacing to the top. Pull the
lacing pin and replace the belt. Only factory supplied belts are recommended and both belts should be
replaced at the same time.
The two belt tensioning brackets are spring loaded with two tension springs on each. Make sure
that these springs are attached to the tension roller bracket after the belts have been replaced.

Pneumatic system
The pneumatic system consists of the filter/regulator, two solenoid valves, one kicker valve, the
gate cylinder and the kicker cylinder. The speed controls for the kicker are located on the kicker valve
manifold. Cushion adjustments are located on the kicker cylinder. The gate speed is controlled by the flow
control located on the main pneumatic assembly. The filter is self-draining. The main regulator setting
should be set at 70-75 psi (4.9 to 5.3 kg/cm²). A lockout valve on the main pneumatic assembly is used to
prevent undesired activation of the pneumatic syste
